Loading Screen

In nanos world it is possible to add a customized and dynamic Loading Screen to your Server using WebUI.

Creating a Loading Screen​

For that, you will need to create a new Package of type loading-screen, and add your HTML/CSS/JS files into the Package's root folder. Your primary HTML file should be called index.html. It will look like that:

└── my-loading-screen/
β”œβ”€β”€ Package.toml
β”œβ”€β”€ index.html
β”œβ”€β”€ style.css
└── ...

Getting Load/Download Progress​

To be able to display dynamic information in the screen, you can listen to the Event UpdateScreen (which will trigger every few ms):

Event UpdateScreen​

messageDisplay the current state (loading, validating, downloading...)
message_secondaryDisplay the current asset/file being loaded or downloaded
progress_smallCurrent small progress
progress_small_totalMax small progress
progressCurrent progress
progress_totalMax progress value
current_stageThe current stage of the load (loading, downloading)
Events.Subscribe("UpdateScreen", function(message, message_secondary, progress_small, progress_small_total, progress, progress_total, current_stage) {
// Update your HTML here

You can use progress and progress_total for filling up the main loading bar, and progress_small for a small/sub loading bar.


Always use progress / progress_total for getting the current % percentage, as progress_total can represent the total amount of files being downloaded for example.

Player Information​

Also, it is possible to fetch Player’s information by accessing a global variable called LoadingScreen:

var LoadingScreen = {

Stop Menu Music​

It is possible to turn off the built-in menu music by calling an event from Loading Screen JS:


Configuring your server to use the Loading Screen​

After creating your loading-screen package, you will need to configure your server to load it in your Config.toml. Just set the setting loading_screen to your Package's folder name.

# loading-screen package to load (the loading screen will be displayed when players join your server)
loading_screen = "my-loading-screen"

Or start it with --loading_screen "my-loading-screen".
